Fonera DD-WRT flashing

LAN ip 192.168.1.250

in DOS ping -t 192.168.1.254

PLUG in FONERA

TELNET in to RedBoot at 192.168.1.254 -p 9000

AND you've got the

That's it. You are ready now to flash FONERA with a new firmware.

1 . Copy root.fs and vmlinux.bin.l7 to your tftp server directory

2. Configure the RedBoot bootloader IP and TFTP server settings using

ip_address -l [local ip address] -h [remote server address]

ip_address -l 192.168.1.254 -h 192.168.1.250

3.

flash the unit by entering the following commands

RedBoot> fis init

Re: Overclocking Atheros devices such as La Fonera Fon/Dir-300

by ngg.online » Tue Mar 30, 2010 10:35 pm

Ok so after reading some more in the DD-WRT forum I found a solution myself. It is almost identical as in the one in the DD-WRT forum, however some commands are a bit different for Gargoyle and the offsets are different for D-Link Dir-300. 

So here is my solution, it is successfully tested on FON2100 and DIR-300:

Log on the the device using SSH, then:

CODE: SELECT ALL

cat /dev/mtdblock0 > /tmp/RedBoot.bin

Now copy the file with scp to your local computer and load it into a hex editor.


* For La Fonera FON2100 (and FON2200 did not test it personaly):
- change offset 0x1e3 from 0x03 to 0x01 (divisor 2 instead of 5)
- change offset 0x1ef from 0x5c to 0x28 (multiplicator 10 instead of 9 = 200 mhz) 

MD5 checksums: 
FON2100 183MHz: D8F123639752F2E56B46606461AD8174
FON2100 200MHz: 6AD647AE0978FFBA4357EFBCF0B4DF98

FON2200 183MHz: 80B1A6D05AE6B420129326F8B77B2FC6
FON2200 200MHz: B12C88742121D42C848C03AC36821F02 

* For D-Link Dir-300:
- change offset 0x17 from 0x03 to 0x01
- change offset 0x23 from 0x5c to 0x28 

MD5 checksums: 
DIR-300 183MHz: B9D638E537D01D3ED651FAB2AF63FC22
DIR-300 200MHz: 713806dbb99cb0e633a385eb1a8b5440

Alternatively, you can also download and use the already modified RedBoot bootloaders attached to this post. They worked for me, but I do not guarantee that they will work for you too.

OK now we just need to flash it back. 
Copy the modified RedBoot.bin back to the /tmp folder of your router and do:

CODE: SELECT ALL

mtd -f write /tmp/RedBoot.bin RedBoot

Then just reboot or replug the power and it will boot up with 200 MHz.

After rebooting you can verify the CPU speed by using SSH and typing the following:

CODE: SELECT ALL

cat /proc/cpuinfo

Hopefully this is useful to someone else as well.
